Modded C63 versus modded M3 is always an entertaining battle. Here we see two modified examples running each other at the dragstrip. The C63 is the camera car with an OE Tuning tune, MHP headers and full exhaust, carbon fiber hood/trunk, race seat, slicks, and no seats. The M3 is a DCT with the VT2-650 kit claiming over 600 wheel horsepower on R-compound tires.

Now, on paper, the M3 should make quick work of this C63 which is not making over 600 wheel horsepower. The weight savings measure on the C63 help but not enough to overcome the supposed power disparity. The end result is 11.2@125 for the supercharged M3 versus 11.0@125 for the C63.

The M3 simply is not making the power it is claiming on the dyno and that is why it lost. An ESS-VT1 535 supercharged M3 running less boost without an intercooler only ran 2 MPH slower at the same strip on the same day. The video is a good educational piece on the difference between racing on the dyno with inflated graphs for bragging rights and in the real world.

So what happened to you not wanting to use it? Get how much better it is now?

The trick to getting the tires heated is a line lock but whatever, you guys do your setup your way and I'll do mine my way.

Yep, the trans will go into limp mode pretty quick. Might be time to look into an upgraded cooler... just a thought.

mine never went into limp mode, nor did AK's..

as for LC, i never ever used it before, but at such an event, i figured why not.. and it did work out wonderfully.

a lineloc is definitely THE WAY to go, but if you dont have one, properly warming the car up, driving around the lot, an attempt at a burnout, a pass, and then restaging is the best way to get the tires heated up.. thats how i got my best runs in..
